Application

(S)-3,3′-Bis(triphenylsilyl)-1,1′-binaphthyl-2,2′-diyl hydrogenphosphate can be used as a catalyst:
  • In the synthesis of 1,3-dioxolochroman skeletons by reacting 3-methyl-2-vinylindoles with ortho-quinone methides.
  • In the exo-selective cyclization of mupirocin methyl ester.
  • In the kinetic resolution of cyclic aliphatic syn-1,3-diols, which are used as valuable building blocks.
